AUTOMATIC VALVE.

SPECIFICATION forming part of Letters Patent No. 653,628, dated July' 10, 1900.

Application filed February 20, 1900. Serial No. 5,967. (No model.)

T0 all whom, t Hetty concern.'

Beit known that I, WILLIAM I-I. PARTON, a citizen of the United States, residing at Syracuse, in the county of Otoe and State of Nebraska, have invented certain new and useful Improvements in Automatic Valves; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object the provision ofa valve of the type which is automatic in operation and controlled by -the change of level of the water contained in a tank, trough,- or other reservoir through the intervention of a pivoted weight-board.

The invention is eminently adapted for stock-watering troughs which require replenishingrin order to maintain the level of the water at a predetermined point.

For a full description ofthe-invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting theresult reference is to be had to the following description and the drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a top planview ofa valve embodying the vital featuresof the invention. Fig. 2 is a side elevation. Fig. 3 is alongitudinal section. Fig. 4 is a detail view of the face-plate having the valve seated. Fig. 5 is a detail view showing the body portion of the valve-casing constructed of wood.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The valve comprises a plate 1, casing 2, and face-plate 3, Iirmly attached, so as to obviate leaky joints, the casing 2 being clamped between the plates 1 and 3 by means of bolts 4. The casing 2 may be of metal or wood, and its exterior may be of circular outline orv of rectangular form in cross-section. An inner flange 5 is provided at one end of the' casing 2 and constitutes a 'shoulder or support for one end of a conical spring 6, the smaller end of said spring receiving a teat 7, projecting from a valve 8, mounted for reciprocating movements in the casing.

The face-plate 3 has a raised portion 9, which snugly fits within the end of the casing 2 remote from the iiange 5, and a packingring 10 is placed exterior to the raised portion 9 and is clamped between the marginal portion of the plate 3 and the end of the casing 2. The central portion of the plate 3 is apertured, and an annular iange 11 projects from the inner face of the plate 3 in line with theopening andrconstitutes a seat for the Valve 8. The stem 12 of the valve 8 is directed in its movements by means of a guidering 13, located in the opening of the plate 3. The side of the valve 8.adjacent to the plate 3 is provided with a disk 14, of leather, rubber, or like material, to make a tight joint with the seat 11. The lvalve opens inwardly against the pressure of the water, ,andthe tension of the spring 6, and these forces combined serve to hold the valve squarely upon its seat, so as tol preclude possible leakage. The stem 12 projects beyondthe outer face of the plate 3 a sufficient distance to be e11- gaged by the butt-end of a pivoted or hinged board. v

The clamp-bolts 4 are located exterior to the casing 2 and pass through openings in the plate l and enter the notches formed in oppositely-disposed lugs 16 of the plate 3. The bolts 4 are preferably of the hook type, and their outer ends project vertically, as shown at 17, to form hinge members for the weightboard 15, the latter being provided at its buttend with eyes 18 to engage over the vertical or hook ends 17. This construction admits of the weight-board beingreadily placed in position and removed when desired.

The weight-board 15 is comparatively narrow and long and is provided at its rear or butt end with screw-eyes 18, which constitute hinge members and are adapted to coperate with the aforesaid vertical extensions 17. By having the parts 18 make screw-threadconnection with the float they can be moved in or out to accommodate the distance between the end of the stem 12 and the rear face of the butt-end of the weight-board, thereby allowing for any variation in the length of the stems of different valves. A cross-piece 19 is IOO ' the supply.

attached to the butt-end of the weight-board 15 and prevents transverse warping thereof. In this connection it is to be understood that the weight-board may be of any construction so long as it will be affected by the change of the level of the water and cause an opening and closing of the valve.

The plate 1 is formed with an opening 20, which is connected with the Water-supply by means of a pipe or in any desired manner. The parts being assembled substantially as shown, the outer end of the Weight-board l5 gravitating forces the butt-end of the ioat against the stem 12 and unseats the valve 8, thereby permitting the water to escape through the opening in the face-plate 3. As the Water rises in the trough or tank and approaches the predetermined level the outer end of the weight-board will rise until all inuence of the weight-board is removed from the valve, when the latter will be seated by the combined action of the spring 6 and the pressure of the water, thereby shutting off Vhen the level of the water recedes by reason of evaporation or the withdrawal of water from the trough or tank, the outer end of the weight-board will descend and cause the valve 8 to open in the manner stated, when the tank will be replenished, the supply being cut off when the water reaches the given level.

The valve involves an exceedingly-simple construction and is accessible for inspection or repairs, and the packing 14 can be replaced when worn or hard at a triiing cost and by the average person without requiring the use of tools other than a wrench forloosening the clamp-bolts Ll. The weight-board can be lifted from engagement with the vertical extensions 17 of the clamp-bolts and can be lowered into position at a moments notice.

The parts 17 may be provided in any convenient way other than making them a part of the bolts 4 so long as they serve to hin gedly connect the Weight-board 15 with the valvecasing.

The plate l may be a side of the trough, a partition therein, or a closure for the entrance end of the casing 2, in which latter instance it is to be attached to the trough or a part thereof by bolts orin any manner found most convenient.

Having thus described the invention, what is claimed as new is- 1. A valve of the character described, cornprising a casing, a face-plate having a valveseat, fastenings for clamping the casing and face-plate together and havingbent end portions, a valve located in the casing and having a protruding stem, and a board having an eye at its butt-end making hinge connection with the bent portion of the aforementioned fastening and adapted to engage with the valve-stem, substantially as set forth.

2. In combination, a casing, plates at opposite ends of the casing and formed with openings in communcation therewith, bolts clamping the plates against the ends of the interposed casing and having the end portions adjacent to the outlet-opening bent, a valvelocated within the casing and having a protruding stem, and a board making hinge connection with the bent ends of the clamp-bolts and adapted to have its butt-end engage with the Valve-stem, substantially as described.

3. In combination, a casing, a face-plate having an opening provided with a guide and having an annular flange in line with the opening and constituting a valve-seat and formed with a raised portion to enter the casing, means for securing the plate to the end of the casing, and a valve opening inwardly and having a stem passing through the guide of the said plate, substantially as set forth.

4f. In combination, a valve-casing having an inner flange at one end, a face-plate having a raised portion to enter the opposite end of the casing and having a central opening, an annular flange in line with the opening and forming a valve-seat, and a guide in said opening, means for clamping the face-plate against the end of the casing, a conical spring located in the casing and having its base portion seated against the inner iange, and an inwardly-opening valve having a stem passing through the guide of the face-plate and having a teat in line with the stem and entering the smaller end of the conical spring, substantially as set forth.

5. In combination, a valve-casing, a plate, bolts for clamping the plate against the casing and having bent end portions, an in- Wardly-opening valve having a protruding stern, a board, and hinged members having adjustable connection with the board and adapted to be loosely connected with the bent ends of the clamp-bolts, substantially as set forth.

In testimony whereof I aix my signature in presence of two witnesses.
